OK, so what does that mean on the trail? I've got a semi-entry level hardtail with a cheap fork. If I shell out the money for a fork upgrade (assuming I could find one that would work with v-brakes), I'll get a more advanced hydraulic system, more adjustability and better feel, right? So when I leave the parking lot and come to the first spot that has a bunch of forearm-sized roots, what difference will I notice? Then when I have to clear a 10" diameter log...how will that be different? After that is a small rock garden, then a little downhill bobsled-ish slalom deal.

I guess I'm asking what does an upgraded suspension fork actually do better than a low-end one?
